I don't like the swear words in the name of the game either, but I respect your reasoning.
If I named my game with a direct translation (Ёбанная планета), I couldn't put it on a public platform in my country. Only on an “underground” one.
You can call it something like “weird” planet, or “utterly bizarre”. The Anglo-American language is really poor at expressing emotion — you can look in French or German for similar terms.
Planète de merde [Planète merdique] already sounds somehow more decent, if only because it is a foreign swear word.
Regarding xyz, he really absolutely organically does not perceive other people's arguments and is not able to agree with them and admit his wrongness. But that's not why we love him. He has another virtue for which he is forgiven here — he is a programming and math genius. I urge you to show him humane leniency, as this knowledge of his can be useful to you as well.
Just a quick note on a factual error.
Having to check the "view adult content" box on YouTube isn't a problem either.
It's a problem. Yt requires registration to view “adult” content, which may not be acceptable to everyone. And sometimes it's just not possible to register there (like we have now).
